Afppiiatimi filed march 9, 190s. serial No. 420,019.

To all whom 'it may concern:

`Be it known that I, WALTER N WAYMAN, a citizen of theUnited'States, residing at Staunton, in thee-county of Augusta and State of Virginia, have invented certain new and useful. Improvementsv in Molds; and I do declare the `following tol be a fullclear,

`and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in molds. l l Theobject of the invention is to provide a hollow mold having means whereby a current of water is caused tocirculate therethrough to keep the molds cool and to pre.

vent burning on, warping, or melting of ,the molds. y

With this and other objects in view, the invention consists of certain novel features of construction, combination and arrangementof parts as will be described andpar- 'ticularly pointed out in the appended claims.

In the accompanyinf drawings, Figure 1 is a side view of a mo dconstructed in acand showing ythe parts in closed position; Fig. 2 is a vertical sectional View of the same, showing the so parts open; Fig. 3 is a' cross sectional view with the parts 1n a closed position; and Fig. 4 is an inner side View of one of the parts or sections of the mold.

Referring ,morejparticularly to the drawings, 1 denotes the mold, which maybe of various forms or shapes, for casting various articles, the same being shown in the present instance -as constructed for casting sash weights. 'The mold is formed -in two hollow sections, 2 and 3, which areformed of metal and'have their inner oryengaging-4 sides depressed' in the proper shape to form the article to be molded. Y l

The mold section,` 2, is preferably supported upon an arm or ar, 4, the'lower end of which is bolted or otherwise secured to 'a suitable base piece, 5. To the lowcr end of the section, 2, is connecteda water inlet pipe, G, said pipe being connected to a main supply pipe, 7. To they opposite end of the section 2 is connected an overflow pipe, 8,'

the opposite end of which isconnected to a main overflow pipe, 9. To the lower end of the mold section 3, is connected a flexible water inlet pipe, 10, the oppositeend of which is connected to the supply pipe, 7, as shown. The upper end of the section 3 has connected thereto a Flexible overflow pipe,

12, theopp'osite end of which is connected to'vv the main overflow pipe. By means of the main and branch su('pply pipes and the overilow pipes connecte to the, upper end of the mold section, acurre'nt of water is caused to circulate' through the mold sections and thus keep the same cool.

Connected to each side'of the stationary mold section 2 are laterally projecting arms, 13, to the outer ends of which are pivotally connected a bell-crank operating lever, 14,

one arm of which forms a handle, 15, while the opposite arm is connected to the movable mold section 3 Aby a link, 16. The mold sec.- tion 3 is referably provided on each side with `ano set.lug, 17, having formed therein 'a guide passage through which the arms 13 extend, said arms thus forming a support upon which the mold section, 3, is adapted to slide when the mold is open or closed. In y closing the mold sections, the handle end of the bell crank lever 14 is swung upwardly, thereby causing the oppositey end to move inwardly and thus force the section 3 of the mold into 'engagement with the stationary section, 2. The flexible water supply and i overflow pi es, 10 and 12, permit the section 3 to be rea ily moved into operative and ino era'tive` ositions. te mold ave been closed, the metal is oured into the upper end-of the depression iormed in the meeting sides of the sections, and the article cast. After the cast articles become cool, the lever, 1,4, is operated to draw the section 3 out of enga ement with the section 2, thus permittin t e article to be dropped out between the ower portions of the mold sections.

From the fore oing description,ltaken in connection with t e accompanying' drawings, the construction and operation of the inven'- tion will bereadily understood without requiring a more extended explanation.

Various changes in the form, roportion and the minor detailsv of construction may be resorted to without departing from the prin- 'ciple or sacrificing any of the advantages of the invention, asdeined in the appended claims. l u

Ilaving thus described my invention, what I claim as new and desire to secure byLctters-Patent, is:

After `the sections of 1. A mold of the character described comrising hollow sections adapted to-be moved into and out of engagement with each other, a mainwater supply ipe, a main overow pipe, and branch supp y and overflow pipes to connect said sections of the mold with said main su ply and overlow pipes, substantially as escribed.

2. A-mold comprisin a plurality of hollow sections', means to hol one of said sections stationary, a water su ply pipe, an inlet pipe connecting saidv su p y ipe 'with said staionary section of tiie mo d, a lejiible supply pipe adapted to connect said movable section with said main supply pipe, a mainoverlow pipe, a branch overflow ipe adapted to connectthe upper end of sai stationary section of the mold with said main overllow pipe, a eXible overflow i e ada ted to connect the othersection o t e mo d with said ymain overlow pipe, and means whereby the movable section of 'the mold is moved into and out of engagement with the stationary section, substantially as described.

3. A mold of the character described comrising a pair of hollow sections, one of' which is held stationary, water su ply and discharge pipes connected to sai sections, supporting arms iXedly mounted on one of said sections and slidably en awed with the opposite section, a bell-cran clever in the carter end of said arm, and a link to connect said lever with said movable section whereby the latter is moved into and out of engagement with the stationary section to close and open 'the mold, substantially as described.

In testimony whereof l have hereunto set my hand in presence of two subscribmg witnesses.
